BACKGROUND OF THE INVENTION Field of the Invention

There is provided a kitchen appliance assembly. In particular, there is provided a kitchen appliance assembly, as well as a method of converting a kitchen having one of a slide-in and drop-in appliance to a kitchen having built-in appliances.

Description of the Related Art

The traditional kitchen range receptacle was designed to connect a single kitchen appliance to a high energy circuit. Traditional kitchen appliances are usually moveable appliances known as slide-in or drop-in appliances which plug into a 220-240 volt outlet via a range receptacle.

Built-in kitchen appliances are desirable because they may allow for greater design flexibility, increased user-friendliness and functionality. However, built-in kitchen appliances may require double wiring to the circuit breaker box of the building, with a separate wire, circuit breaker and range receptacle for each built-in appliance, and in some cases may require an upgrade of the circuit breaker box to accept additional circuits. Also, quite often the main breaker box is located a great distance from the existing kitchen wiring. The conversion may thus require costly alterations to the building structure to access and convert the wiring to power built-in appliances. Such a renovation can thus be expensive due to increased electrician costs and increased labor costs associated with removing extensive amounts of wall and thereafter repairing the same. There are also permit, drawing, and related government fees.

There may accordingly be a need for a more cost-effective method of converting a kitchen having one of a slide-in and drop-in appliance to a kitchen having built-in appliances.

The housing 106 has a front 108 seen in FIG. 6, a rear 110 seen in FIG. 7, a pair of spaced-apart ends 112 and 114 seen in FIG. 6, and a pair of spaced-apart sides 116 and 118 seen in FIG. 6 that extend between said ends thereof. The front and rear of the housing are rectangular and extend between the ends and the sides of the housing. The front 108 and the rear 110 of the housing 106 are similar in size and larger than the sides 116 and 118 and the ends 112 and 114 of the housing in this example.

As seen in FIG. 6, the proximal end 113 of the cable protector 111 couples to and extends from side 116 of the housing 106 via a hose coupling member 125 at a location adjacent to end 114 in this example. As seen in FIG. 7, the cable protector extends from the housing adjacent to the rear 110 of the housing in this example.

The housing 106 includes a removable cover 120 aligned with the front 108 thereof and which is selectively removable to reveal the interior 122 of the housing of the power strip 97. The cover is shaped to extend about the open top 119 of the housing. The cover 120 includes a planar member in this example a rectangular plate 121 which aligns with the front 108 of the housing 106 when the cover is fitted in place as seen in FIG. 6. The cover includes a peripheral portion 123 which couples to and extends outwards from plate 121.

In this example, the fasteners extend through the peripheral portion of the cover and into the ends 112 and 114 of the housing 106 at locations adjacent to the sides 116 and 118 of housing. The fasteners 151, 153, 155 and 157 securely couple the cover to the sides and the ends of the housing thereby.

As seen in FIG. 7, the power strip apparatus 96 includes a pair of mounting members, in this example in the form of mounting plates 124 and 126 which extend along the rear 110 of the housing of the power strip 97. Mounting plate 124 couples to and extends outwards from side 116 of the housing 106 in this example. Cable protector 111 couples to the housing 106 adjacent to mounting plate 124 in this example. Mounting plate 126 couples to and extends from side 118 of the housing in this example. Each mounting plate has at least one aperture extending therethrough. This is seen in FIG. 7 by fastener apertures 127 and 128 extending through mounting plates 124 and 126. As seen in FIG. 5, the power strip 97 is connectable to wall 22.1 via fasteners 129 which extend through the fastener apertures of the mounting plates in this example.

Referring to FIG. 6, the power strip 97 includes a plurality of electrical range sockets, in this example three range sockets 130, 132 and 134 electrically coupled to the range plug 104. However, this number of sockets is not strictly required and there may be as few as two, or more than three in other embodiments. The electrical sockets mount to and partially extend through circular apertures 131 of the planar member 121 of the cover 120 in this example. The cover 120 may thus be referred to as a removable front to which the electrical sockets 130, 132 and 134 are mounted.

As seen in FIG. 6, socket 130 is adjacent to end 112 of the housing 106 and is adjacent to side 116 of the housing in this example. Socket 134 is adjacent to end 112 of the housing and is adjacent to side 118 of the housing in this example. Sockets 130 and 134 align with each other in this example, and socket 132 is between and offset at least in part from sockets 130 and 134 in this example. Sockets 130, 132, and 134 have first half portions 194, 196 and 198, respectively, and second half portions 200, 202 and 204, respectively. In this case, the first half portion 196 of socket 132 aligns with both the second half portion 200 of socket 130 and the second half portion 204 of socket 134. Socket 132 is adjacent to end 114 of the housing 106 and is between the sides 116 and 118 of the housing. Socket 132 in this example is halfway between the sides 116 and 118 of the housing.

Referring to FIG. 6, each of the electrical sockets has a cross-sectional diameter, as shown by diameter D for socket 134. Adjacent ones of the sockets, namely sockets 130 and 132, and sockets 132 and 134, are spaced from each other by a distance L which is equal to or greater than one half of said diameter D in this example.

The width W of the housing 106 extending between ends 112 and 114 is preferably in the range of equal to or greater than two times said diameter D and equal to or less than three times said diameter D, in this example. More preferably, the width W of the housing 106 is generally equal to two times said diameter according to one embodiment.

The length L of the housing extending between sides 116 and 118 is preferably equal to greater than four times said diameter for a housing having three sockets 130, 132 and 134. The length of the housing is generally equal to about five times said diameter in this example.

The range plug 104 and sockets 130, 132 and 134 include second electrical terminals 152, 154, 156 and 158 coupled together in series via conduits, in this example wires 160, 162 and 164, respectively. The range plug 104 and sockets 130, 132 and 134 include third electrical terminals 166, 168, 170 and 172 coupled together in series via conduits, in this example wires 174, 176 and 178, respectively. The range plug 104 and sockets 130, 132 and 134 include fourth electrical terminals 180, 182, 184 and 186, respectively, coupled together in series via conduits, in this example wires 188, 190 and 192, respectively.

As seen in FIG. 2, the kitchen appliance assembly 26.1 includes a plurality of built-in kitchen appliances, in this example including a first energy-efficient kitchen appliance in the form of an energy-efficient cooktop N integrally built into countertop 42.1. The kitchen appliance assembly 26.1 further includes an additional cabinetry below the cooktop in the form of lower drawers 62 and 64. The cooktop N and lower drawers replace range 48 seen in FIG. 1.

As seen in FIG. 3, the cooktop includes a plurality of heating elements 66 for cooking items enclosed within pots (not shown) for example. Each of the heating elements provides a maximum temperature thereon in operation, with a given temperature of the heating elements being shown as T_(N) in FIG. 9. Referring back to FIG. 3, the cooktop N includes actuator buttons 68 operatively connected to the heating elements. The actuator buttons selectively turn the heating elements on or off and adjusting the amount of heat emitted from the heating elements. The built-in cooktop to this stage is conventional, with its parts and functionings being known to those skilled in the art.

Referring to FIG. 9, the cooktop draws a given current amperage I_(N) and has a current rating I_(MAX1), which is equal to a maximum threshold amount of current drawn to be drawn by the cooktop. The amperage range is from 0.5 amps to 29 amps with use of a short-timed boost cycle, special heat lift up, according to one example.

Referring to FIG. 3, the cooktop N further includes a safety mechanism 70 and electrical circuitry 72.

Referring to FIG. 3, two of the heating elements of the cooktop may be controlled by a relay, triac and thermostat, and the other two of the heating elements may be controlled by a relay and thermostat in this example. According to another aspect, if the inner housing temperature of the cooktop N is above a set threshold, such as 200 degrees Celsius, then thermostat is configured to automatically switch off to protect the cooktop. After the inside of the cooktop has cooled down, the thermostat is configured to enable the cooktop to operate once more.

As seen in FIG. 9, the safety mechanism further includes at least one of an internal fuse and a circuit breaker for each heating element 66, in this example shown by internal fuse 74. If the thermostat is broken and the cooktop N is overheating, the fuse functions to shut off the power supply to the given heating element of the cooktop. The fuse may be configured such that it melts upon the current drawn through the electrical circuitry of the cooktop reaching a maximum threshold, with the current level at which the fuse melts being I_(MAX1). The overtop N is powered down upon the fuse 74 melting, as shown by box 77 in FIG. 9.

As seen in FIG. 3, the cooktop N includes a plug for a range receptacle, in this example a range plug 78 electrically connected to the electrical circuitry 72 thereof. As seen in FIG. 5, any of the sockets, and in this example socket 132 of the power strip 97 is shaped to receive range plug 78 of cooktop N seen in FIG. 3.

Referring to FIG. 2, the plurality of built-in, energy-efficient kitchen appliances of kitchen appliance assembly 26.1 includes a second energy-efficient kitchen appliance, in this example an energy-efficient oven N+1. The oven is positioned at a location spaced-apart from the cooktop N in this example. The oven N+1 in this example is integrally installed within or built into the column of cabinetry 31, with the oven taking the place of cabinet 34 and drawer 36 of the kitchen appliance assembly 26 seen in FIG. 1.

As seen in FIG. 4, the oven N+1 includes an enclosed heating element 80 that is selectively accessible via a hinge oven door 82. The oven N+1 includes actuator buttons 84 operatively connected to the heating element. The actuator buttons selectively turn the heating element on or off and adjusting the amount of heat emitted from the heating element. The built-in oven to this stage is conventional, with its parts and functionings being known to those skilled in the art.

Referring to FIG. 9, the oven N+1 draws a given current amperage I_(N+1) and has a current rating I_(MAX2), which is equal to a maximum threshold amount of current drawn to be drawn by the oven. The amperage range of the oven may be 5 amps to 10.5 amps according to one example.

Referring to FIG. 4, the oven N+1 further includes electrical circuitry 86 and, as seen in FIG. 9, a safety mechanism 88. The safety mechanism 88 of the oven includes a thermostat 92 in this example operatively connected to the heating element 80 of the oven seen in FIG. 4. Referring back to FIG. 9, the thermostat is configured to automatically regulate the temperature T_(N+1) of the heating element, with the thermostat periodically powering down the heating element, as seen by box 93 in FIG. 9, and automatically-resetting upon detecting a maximum temperature of the heating elements of T_(MAX2). After the oven has cooled down, the thermostat 92 enables the oven to operate once more.

Referring to FIG. 9, the safety mechanism further includes one of an internal fuse and circuit breaker, in this example internal thermal fuse 90. If the thermostat 92 is broken and the oven is overheating, the fuse functions to shut off the power supply to the oven. The fuse is configured such that it melts upon the current drawn through the electrical circuitry of the oven N+1 reaching a maximum threshold, with the current level at which the fuse melts being I_(MAX2). The oven is powered down upon the fuse 90 melting, as shown by box 93 in FIG. 9.

Referring to FIG. 4, the oven N+1 includes a plug for a range receptacle, in this example a range plug 94 electrically connected to the electrical circuitry 86 thereof. As seen in FIG. 5, any of the sockets, and in this example socket 134 is shaped to receiving range plug 94 of oven N+1 seen in FIG. 4.

As seen in FIG. 9, the plurality of built-in, energy-efficient kitchen appliances of kitchen appliance assembly 26.1 may include additional energy-efficient kitchen appliances, in this example shown by built-in appliance N+2. The appliance includes a safety mechanism 87 in the form of a thermostat 89 in this example operatively connected to the heating element of the appliance. The thermostat is configured to automatically regulate the temperature T_(N+2) of the heating element, with the thermostat periodically powering down the heating element, as seen by box 95 in FIG. 9, and automatically-resetting upon detecting a maximum temperature of the heating elements of T_(MAX3). After the appliance N+2 has cooled down, the thermostat 89 enables the oven to operate once more.

The appliance draws a given current amperage I_(N+2) and has a current rating I_(MAX3), which is equal to a maximum threshold amount of current drawn to be drawn by the oven. The appliance N+2 further includes an internal breaker or fuse, in this example fuse 89 which melts upon the current I_(N+2) drawn through the appliance reaching a maximum threshold, with the current level at which the fuse melts being I_(MAX3). The appliance is powered down upon the fuse 89 melting, as shown by box 95 in FIG. 9.

In operation and referring to FIG. 9, electrical power is supplied to the heating elements of the cooktop N, oven N+1 and appliance N+2 to performing cooking tasks and the like. The fuses 74, 90 and 89 of the safety mechanisms 70, 88 and 87 of the built-in appliances determine whether the current amperage I_(N), I_(N+1) and I_(N+2) drawn from the appliances is larger than the maximum current rating I_(MAX1), I_(MAX2) and I_(MAX3) of the fuses, respectively. If so, respective ones of the fuses melt and said respective one of the appliances N, N+1 and N+2 is powered down as shown by boxes of numerals 77, 93 and 95.

If the current levels are determined to be below the above mentioned maximum thresholds, each of the safety mechanisms 70, 88 and 87 may also employ thermostats 76, 92 and 89 which automatically power down the respective heating elements of the appliances, as shown by boxes of numerals 77, 93 and 95, upon the temperatures T_(N), T_(N+1) and T_(N+2) thereof reaching maximum threshold temperatures T_(MAX1). T_(MAX2) and T_(MAX3). This temperature threshold may be configured to vary from one appliance to another.

If the detected temperatures on the heating elements of the cooktop N, oven N+1 and appliance N+2 are below the pre-set thresholds, as a third level of safety, the built-in kitchen appliances of kitchen appliance assembly 26.1 are selected such that the collective current amperage thereof is equal to or less than that of a maximum collective amperage threshold, which in this example is equal to that of the current rating I_(F) of breaker 206. If the current detected from the sum of the currents I_(N)+I_(N+1)+I_(N+2) . . . etc. drawn from appliances N, N+1, N+2 etc. collectively is less than the current rating or amperage or amperage I_(F) of breaker 206, the cooktop N, oven N+1 and appliance N+2 may continue to operate, as shown by box 208 in FIG. 9. If the collective current drawn exceeds I_(F), the circuit breaker 206 trips causing the appliances N, N+1, N+2 etc. to power drawn, as shown by box 210.

Herein described therefor is a method of converting a kitchen having one of a slide-in and drop-in appliance electrically coupled to a range receptacle, as shown by kitchen appliance assembly 26 in FIG. 1 having slide-in electric range 48 connectable to range receptacle 44, to a kitchen having built-in appliances, as shown by kitchen appliance assembly 26.1 seen in FIG. 2 with built-in cooktop N and oven N+1.

Many advantages result from the structure of the present invention. The assembly and method as herein described eliminates the need to trace and change the existing wiring all the way back to the main panel, thereby saving a considerable amount of wiring which could be in the order of 50 feet, for example. The power strip apparatus 96, 96.1 enables the user to convert existing wiring by connecting the power strip apparatus to the existing range receptacle 44 of the traditional kitchen. This saves on construction materials to allow redesigns to be performed without costly conversion of existing wiring. The assembly and method of conversion may thus not require a custom installation, saves wiring costs that would otherwise be required during a custom installation. The power strip apparatus 96, 96.1 may thus enable one to convert the existing wiring of a traditional kitchen appliance assembly to accept up to three energy efficient built appliances into a 240 Vac, 50 A, 60 Hz, 1 phase outlet that is already in place from the existing wiring.

The kitchen appliance assembly 26.1, 26.2 may thus comprise a low cost solution for the problem of converting existing a kitchen appliance assembly having a single traditional high-energy appliance to a kitchen appliance assembly with a plug and play design of built-in kitchen appliances.

The kitchen assemblies 26.1, 26.2 and related method of conversion as herein described facilitate replacement of existing traditional appliances with upgraded, energy efficient modern appliances, thereby functioning to save further costs for the owner of the building. This is especially prudent for kitchen spaces that have limited room so the new space saving appliances can provide more working room to the existing kitchen footprint. The modern kitchen often requires two or three 240/10-20 Amp appliances to be used. The power strip apparatus 96, 96.1, enables the user to readily connect up to three energy-saving, built-in appliances into the existing range receptacle connection. This provides an easy appliance converter for a seamless installation.

The power strip apparatus 96, 96.1 and associated method of conversion enables the redesign of kitchen layouts to be flexible and accepts the modern energy saving appliances in the existing blueprint. The power strip apparatus 96, 96.2 as herein described may be sold as an accessory for modern kitchen appliances, where the apparatus functions to convert the traditional range receptacle connection while inhibiting costly conversions associated with the existing wiring. The power strip apparatus enhances ease of installation for remodeling, upgrading or new installation in prewired buildings.

The kitchen assemblies 26.1, 26.2 as herein described function to remove rodent-attracting cracks in the kitchen cabinetry that may exist in kitchens having slide-in or drop-in appliances. The kitchen assemblies as herein described may thus function to inhibit the presence of rodents.

The assemblies 26.1 and 26.2 as herein described may enable the user to configure more appliance positions and variations with less work while meeting relevant electrical codes and safety standards. The assemblies and methods may also improve safety compared to pigtail methods of coupling together appliances, which may be illegal and void building insurance.

The kitchen assemblies 26.1, 26.2 comprises three layers of safety: 1) each appliance incorporates a thermostat with an auto-reset feature upon the appliance reaching a maximum temperature threshold; 2) each appliance includes a thermal fuse should the thermostat fail or be broken, with the fuse melting and cutting off power to the appliance upon the current drawn through the appliance reaching a maximum current rating; and 3) the assemblies incorporate an in-line circuit breaker which shuts off power to all of the appliances upon the collective current being drawn exceeding a maximum collective current rating.

The need in the market for a built-in kitchen style is strong. Esthetics may place a built-in kitchen as the most valuable. But today that value may be further needed because now that no DDT is allowed, the presence of bugs, mice, and the like in one's kitchen may have increased faster than ever before. A slide-in or drop-in stove may facilitate the presence of crumbs and the like—food for bugs and mice, which may increase an infestation. The world is demanding a cleaner home/kitchen.

The built-in kitchen assembly as herein described, and method of installation thereof, may comprise a cost-effective solution that meets the above need and enables poison and/or traps to inhibit such infestations.

It will be appreciated that many variations are possible within the scope of the invention described herein. For example, instead of being mounted to the wall, the power strip may be walled-in and positioned within the interior structure of the wall in other embodiments. In this case, the power strip may be mounted between the wall studs or on one of the wall studs, for example.

In a further variant, the power strip apparatus may comprise cable free of a cable protector.
